SAFETY RAZOR Filed Dec. 22. 1930 12 2/6 z'zfor Patented Oct. 24, 1933PATENT OFFICE SAFETY RAZOR Jean U. Kore, New York, N. Y., assignor toFlexo Safety Razor Corporation Application December 22, 1930 Serial No.503,921

2 Claims. (01. 30-12) This invention relates to razors and particularlyto that class thereof shown in my 00- pending application Serial No.502,020 filed December 13, 1930 and is in the nature of an improvementthereon.

It has for its object to produce a razor in which the blade willautomatically find its seat on the head of the razor. I

Also it has for its object a blade and guard so fashioned that the bladewill be laid equally and surely on the curved head of the razor.

Other objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawing wherein the preferred form of embodiment of the invention isclearly shown, and in which similar numerals of reference denote similarparts throughout the several views.

Figure 1 is a side elevation of the blade, guard and head with a portionof the handle connecting the same.

Fig. 2 is a section on only.

Fig. 3 a flat View of the ordinary razor blade.

Fig. 4 is a similar view of the improved blade.

The invention is constructed and operated substantially and preferablyas follows:

1 is the blade, 2 the head, 3 the guard, 4; the handle, 5 the usualthreaded portion or shank of the head, and 6 the threaded portion in thehandle to receive the threaded portion of the head.

The head 2 a section of which is more particularly shown in Fig. 2,instead of having its lip, or apron, or bent over cam portion 15 madesquare to the base 16 as along the line 1'7, 17, is laid at a moreobtuse angle thereto as along the line 18, 18. The hole 19 of the razorblade of necessity must be made somewhat larger than the shank orthreaded portion 5 so as to slip easily thereover; but when clampedtight by the handle it has no sure back rest. But by giving room for theblade to pass easily over the shank, and then automatically pushing theblade against a back as at 20 when the handle is screwed on, bothrequirements are met.

The improved blade 1 is shown more particularly in Fig. 4 and has anoblong opening 21 cut therein curved inwardly toward the middle portionas at 22; also four small projections or locators 23 into which theshank 5 passes and is held thereby.

It has been found that if a thin blade as ordinarily constructed beclamped along a curve as shown in Fig. 1 it will bend unevenly along the2-2 of Fig. 1 of the head backing 20 due to some parts of the bladebeing stiffer than others so that the back 31 of the blade when curvedwillnot fit along the back or portion 20 evenly. But by constructing theblade with the open portion 21 to approximately the shape shown thisunevenness will be avoided. This will give the cutting edge of the bladea longer life, and the person using the blade more satisfaction whileshaving.

The locators 23 prevent the shank 5 from slipping in any direction, andthe same may be rounded off on the inside as shown at 33 the more easilyto fit the shank.

As my invention is in some of its aspects generic, I do not limit myselfto the particular 7 construction shown and described, but alsocontemplate the employment of such equivalents as fairly fall within thescope of the claims.

In this connection I may state that the sloping back or scarf 15 may beused on razors hav- 7 ing straight heads as well as curved heads asshown in Fig. 1. Instead of having the backing 20 mounted along thestraight line 18-18, it may be mounted along the curved line 30-30 ifdesired.

Therefore it should be understood that I may make various changes in theform, proportion, size and detail of the several parts shown, as well asthe number and position of certain elements used, without departing fromthe spirit of the invention.

I claim: a

1. In a safety razor, a flexible blade, a blade holder comprising alongitudinally curved head having a shank thereon and a flexible guardgohaving a hole to receive the shank, cam members on one edge of the headfor engaging one edge of the blade and of the guard and cooperating withthe shank to align the blade and the guard, and means on the shank tohold the blade and the guard on the head and to bend themlongitudinally.

2. In a safety razor, a flexible blade, a blade holder comprising alongitudinally curved head having a shank thereon and a flexible guardhaving a hole to receive the shank, a cam member at each end of the headat one edge for engaging one edge of the blade and of the guard and 00-operating with the shank to align the blade and V the guard, and ahandle threaded on the shank and engaging the guard to hold the guardand the blade on the head to bend them longitudinally.
